Structure containing array of structure

I want to use a structure that contains an array of another structure.
Something like that :

    Type tPost
    	sSkillsList() as string
    End Type
    Type tRaceParams
    	sPostsList() as tPost
    End Type
Global raceDatas as tRaceParams

It seems that this declaration is correct but I can’t redimension the array sPostsList().
I search and found nothing about this kind of structures or how to use it.
Is it possible to have such thing? What am i doing wrong?

Use this:

Dim newList(3 To 5) As tPost
raceDatas.sPostsList = newList

Thanks a alot!
Seems a bit strange to have to use another variable this way but it work ^^.
